| Abstract: | The geological conditions at Nanjing Hexi is poor, and has abundant groundwater, so a deep foundation pit construction have a significant impact on vicinity existing metro shield tunnel structure and train operation safety. This paper analyzes the impact of deep foundation pit construction on operational shield tunnel at Nanjing metro. Based on this, the paper puts forward the systematic monitoring measures against defects of shield tunnel structure, structural deformation and key equipment, and good results have been achieved. |
